CAUTION ON REPLACEMENT OF OPTICAL PICKUP
The laser diode in the optical pickup block is so sensitive to
static electricity, surge current and etc., that the components
are liable to be broken down or its reliability remarkably
deteriorated.
During repair,carefully take the following precautions.
(The following precautions are included in the service
parts.)
PRECAUTIONS
1.Ground for the work-desk.
Place a conductive sheet such as a sheet of copper
(with impedance lower than 10 Mohm) on the work-
desk and place the set on the conductive sheet so that
the chassis can be grounded.
2.Grounding for the test equipments and tools.
Test equipments and toolings should be grounded in
order that their ground level is the same the ground of
the power source.
3. Grounding for the human body.
Be sure to put on a wrist-strap for grounding whose
other end is grounded.
Be particularly careful when the workers wear
synthetic fiber clothes, or air is dry.
4. Select a soldering iron that permits no leakage and
have the tip of the iron well-grounded.
5. Do not check the laser diode terminals with the
probe of a circuit tester or oscilloscope.
